Beyonce will sing live at the Super Bowl and sent a message to her doubters during a press conference today.

The lip-synching beauty belted out the national anthem on live television this afternoon to prove she still has the pipes to perform one of music’s toughest songs.

In her first words since she was exposed for faking her performance at President Obama’s inauguration, Beyonce promised she’d sing for real at halftime of the Super Bowl.

“I will absolutely be singing live,” she said. “This is what I was born to do — born for.”

Beyonce said she sang along with a prerecorded version of herself at the inaugural because she didn’t have time to practice with the Marine Corp band.

“I could not rehearse with the orchestra because I was practicing for the Super Bowl,” she said.

Beyonce said Sunday’s big gig will fulfill a lifelong dream for hers.

“This has been an aspiration for me,” she said. “Thank God that I’m given this opportunity. You work very hard for these moments and I’m just hoping that all of my life lessons and all my experience, all I can feel I can use for this performance.”

New York song bird Alicia Keys is set to sing the national anthem — presuambly live.

Oscar winner and one-time “American Idol” hopeful Jennifer Hudson will team up with Sandy Hook Elementary School kids to sing “America the Beautiful” before kickoff, the NFL announced today.

The school chorus features 26 kids from the Newtown, Conn., campus. The 26 kids represent the 20 classmates and six educators who were gunned down during a Dec. 14 rampage.
